Genome-enabled prediction of meat and carcass traits using Bayesian regression, single-step genomic best linear unbiased prediction and blending methods in Nelore cattle
(2021-01-01)
Several methods have been used for genome-enabled prediction (or genomic selection) of complex traits, for example, multiple regression models describing a target trait with a linear function of a set of genetic markers. ...
Pollinator-mediated selection in a specialized pollination system: matches and mismatches among populations
(Wiley Blackwell Publishing, Inc, 2010-09)
Most studies on pollinator-mediated selection have been performed in generalized rather than specialized pollination systems. This situation has impeded evaluation of the extent to which selection acts on attraction or ...
Selection of artichoke plants and analysis of correlation between quantitative traits for fresh consumption
(Universidad Nacional de Córdoba. Facultad de Ciencias Agropecuarias, 2015)
The goals of the present study were to evaluate and select artichoke plants suitable for fresh consumption and to establish correlations between quantitative traits. Clones from 39 accessions were obtained from the germplasm ...
The genetic dissection of quantitative traits in crops
(Pontificia Universidad Católica de Valparaíso, 2010)
Do pollinators simultaneously select for inflorescence size and amount of floral scents? An experimental assessment on Escallonia myrtoidea
(BLACKWELL, 2006-11)
Correlation among phenotypic traits may be explained by correlational selection, the simultaneous selection of more than one trait, or by genetic and/or developmental factors. In Escallonia myrtoidea, a tree with scented ...
Phenotypic selection under two contrasting environments in wild sunflower and its crop‐wild hybrid
(Wiley Blackwell Publishing, Inc, 2019-06-05)
Hybridization is a common phenomenon in plants and can lead to the introgression of alleles from one population into another, generate new hybrid lineages, or cause species extinction. The environmental conditions and the ...
Genetic analyses on bodyweight, reproductive, and carcass traits in composite beef cattle
(2017-01-01)
In beef cattle, growth, reproductive, and carcass traits have been studied for improving productivity and quality of meat products. The aim of this study was to estimate genetic parameters for birth (BW), weaning (WW) and ...
The search for Pleiades in trait constellations: functional integration and phenotypic selection in the complex flowers of Morrenia brachystephana (Apocynaceae)
(2014-03-18)
Pollinator‐mediated natural selection on single traits, such as corolla tube or spur length, has been well documented. However, flower phenotypes are usually complex, and selection is expected to act on several traits that ...
Association of RUNX2 and TNFSF11 genes with production traits in a paternal broiler line
(Funpec-editora, 2017-03-24)
Intense selection for production traits has improved the genetic gain of important economic traits. However, selection for performance and carcass traits has led to the onset of locomotors problems and decreasing bone ...
